The same rkhunter has no problem with LibreOffice, Build ID:
165a79a-7059095-e13bb37-fef39a4-9503d18, also an official rpm for Linux
But LibreOffice-3.5 only use one socket, the /tmp/OSL_PIPE one. 

Is there a way to turn off these extra sockets in 3.6 ?


I can't replicate on the deb version with:
Rootkit Hunter version 1.3.8

What version of rkhunter & have you:
 rkhunter --update
to ensure that your rkhunter is up to date?

Version (Build ID: 932b512)

I won't be able to check an rpm version until later - sorry.


Thanks for your reply. I'm using a rpm ;), it is rkhunter-1.4.0-1.el5.

Of course I can get rkhunter silent with something like
DISABLE_TESTS="hidden_ports" or ALLOWPROCLISTEN="soffice.bin".
In this case it will not complain about LibreOffice listening on
the network... even when I open a file with some malware inside.

Can you check the output of this command :
lsof -U | grep soffice

With LibreOffice-3.5, I get only one line (/tmp/OSL_PIPE_...), but
with LibreOffice-3.6 I get two more lines, two unix sockets.
